Infrared spectroscopy of helium nanodroplets: novel methods for physics and chemistry

摘要: Helium nanodroplets have emerged as a new and exciting medium for studying the structure dynamics of both this quantum solvent impurities that can be doped into (onto) grown inside (on surface) droplets. Spectroscopic studies these molecular provide detailed information on helium its interaction with solute. This is particularly important given completely transparent to photons below 20 eV, making direct spectroscopic study liquid problematic. Since an extremely weak solvent, corresponding perturbations spectrum solute molecules are often minor; really only evident because high resolution achieved in such studies. As result, nanodroplet spectra resemble gas-phase results. Indeed, case rotational spectroscopy, Hamiltonian sufficient describe system, effects being to...
